A photo with the post shows off Beauregard's ring: a simple gold band with a solitary sparkling diamond. Berner explains that the two celebrated the good news on Wednesday morning (April 27) with "our favorite and most important meal of the day, breakfast."

Founded in 2004, Edens Edge -- Berner, Hannah Blaylock and Cherrill Green -- moved to Nashville in 2007 and signed with Big Machine Label Group in 2010. In 2013, Blaylock left the trio, and Edens Edge parted with with BMLG; at the time, Berner and Green said that they were committed to continuing to make music together.

Native Run, meanwhile, are signed to Show Dog Universal and are working on their major-label debut. Beauregard and duo partner Bryan Dawley released "Good on You" as their first single in June of 2014.
